Let's evaluate the expressions step by step to find the value of $$ f(-1) \times g(-1) $$.

1. **Calculate $$ f(-1) $$:**
   $$
   f(x) = x^2 + 1
   $$
   Substitute $$ x = -1 $$:
   $$
   f(-1) = (-1)^2 + 1 = 1 + 1 = 2
   $$

2. **Calculate $$ g(-1) $$:**
   $$
   g(x) = 3x + 5
   $$
   Substitute $$ x = -1 $$:
   $$
   g(-1) = 3(-1) + 5 = -3 + 5 = 2
   $$

3. **Multiply $$ f(-1) $$ and $$ g(-1) $$:**
   $$
   f(-1) \times g(-1) = 2 \times 2 = 4
   $$

**Answer:** 4
$$ f(-1) \times g(-1) = 4 $$
